CVE-2009-3547 kernel: fs: pipe.c NULL pointer dereference

This update fixes the following security issues :

- a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel:
pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)

The system must be rebooted for this update to take effect.


Update the affected packages.
